前言

      本书根据2016年改革后的SAT考试（以下简称新SAT考试）内容编写而成。如果正在备考SAT考试数学部分，那么以下简单易行的“四步”学习计划正是考生所需了解与掌握的：

STEP 1.

Know what to expect on test day.

STEP 2.

Become testwise.

STEP 3.

Review SAT Math topics and SAT-type questions.

STEP 4.

Take practice exams under test conditions.

STEP 1 KNOW WHAT TO EXPECT ON

TEST DAY

      章介绍SAT考试数学部分的形式、类型和题目要求。在正式考试中，这些信息不仅会为考生节约宝贵的时间，还会增加自信，避免因为没有充分理解题目要求而出现错误。

STEP 2 BECOME TESTWISE

      第二章是极其重要的一章，主要讲解了SAT考试数学部分的基本解题技巧。学习这些解题技巧以及整本书中穿插的数学知识点将会帮助考生提高做题速度和正确率，进而取得高分。此外，本章还介绍了新SAT考试数学部分中新增的考点。

STEP 3 REVIEW SAT MATH TOPICS AND

SAT-TYPE QUESTIONS

      新SAT考试数学部分依然注重高中课本上的基本概念，但解题技巧与策略却有所不同。第三章至第六章是一个简短的数学复习课程。在这些章节中，考生可以发现大量按章节知识点设置的数学题目，它们都是围绕新SAT考试数学部分四大核心内容展开的：代数核心内容、问题求解与数据分析、高数基础以及其他一些基本的数学问题（如几何关系和三角关系）。因此，无论是自主复习，还是参加补习班进行复习，简单易行的概念介绍和课程设置都使得本书成为SAT考生的理想伴侣。同时，对于练习题目和样题，书中还附有详细的答案和解题思路。

STEP 4 TAKE PRACTICE EXAMS UNDER

TEST CONDITIONS

      俗话说：熟能生巧！本书后一章提供了两套完整的新SAT考试数学模拟试题，并且附有答案和详细的解析。考生好能模拟考试环境来完成这些试题，以便在实际考试中很好地把握答题时间。此外，这些试题也可以帮助考生发现并消除复习过程中的任何薄弱环节和知识漏洞。
